I got a new Hub5 about 8-10 weeks ago. In the last couple of weeks some devices can connect to the WI-FI but they don’t have Internet so pretty useless.This is only on some devices and mainly seems to be laptops.However these devices appear to be able to get internet on the Guest network?I’ve been reading around this and it seems you can only have 255 DHCP connections and Hub5 doesnt seem to be recycling IP addresses on the DHCP server.is there anything I can do to fix this please?

There are times when I think "thankfully I have my own networking kit" I really don't think I could cope with the stress otherwise ......... ;-)

I’m having the very same problem for the second time after having my Hub 5 replaced just 4 months ago after months of not being listened to by Virgin. My home security and heating devices still function fine on the main WiFi network, but a variety of Windows, Android and Apple devices do not - they connect but have no internet and generate “no valid ip configuration’ errors. The same thing happens with both WiFi and Ethernet connections, but the same devices work fine on the guest network. @VirginMedia why have you still not fixed this issue with your Hub?

Trouble is the tech support people know very little because your question is not in their script/playbook and they are not technically trained. It would be VM’s fault if the Hub 5 DHCP was not releasing IP addresses, but to confirm that, someone would need to go into the Hub’s GUI and check the allocated IP addresses against the devices known to be attached. However, there are enough IP addresses in the range for this not to occur unless every address has been used and not released. So, people suffering this phenomenon, need to get someone into the home who understands network basics to check all this out.

DHCP server issues were quite common in the early versions of the Hub 5 Software.Which version of Software is on your Hub 5 ? (with our Hub's menu this is seen from Admin >> Info )

Hubs not that well tested and when we have a issue VM think we are the problem so use hub in modem mode that been tested to work with people who just want the internet we pay for with are own router with 1Gb ports or better

Same issues here now on my 2nd Hub 5 - replied to a similar thread a few days ago and again today. https://community.virginmedia.com/t5/Networking-and-WiFi/WIfi-has-no-valid-IP-configuration/td-p/5509439/page/6
Issue is 100% Dhcp related and soon as that lease time is up it has issues, default lease is 1 day I've increased mine to 7 days, but hoping to go modem mode and hook my own Asus Mesh back up. However this doesn't resolve the problem.

VM this needs fixing.

My current hub software is
Software version
LG-RDK_7.6.20-2306.5? not sure if this is only or new
